<!-- $$$QtQuick-description -->
<div class="descr"> <a name="details"></a>
<p><a href="qtquick-index.html">Qt Quick</a>模块提供图形化的基本类型。只有当QML文档导入<code>QtQuick</code>名字空间时，这些类型才在QML文档中可用。</p>
<p><code>QtQuick</code>模块的当前版本是2.11版本，因此可以通过以下语句导入:</p>
<pre class="qml">

  import QtQuick 2.11

</pre>
<p>有关<a href="qtquick-index.html">Qt Quick</a>的核心概念的更多信息，请访问<code>QtQuick</code>模块文档。</p>
<a name="submodules"></a>
<h2 id="submodules">子模块</h2>
<p>Qt Quick包含如下几个子模块：</p>
<ul>
<li><a href="qtquick-xmllistmodel-qmlmodule.html">XML List Model</a> - 包含用于从XML数据创建模型的类型</li>
<li><a href="qtquick-localstorage-qmlmodule.html">Local Storage</a> - 包含<a href="../qtsql/qtsql-attribution-sqlite.html#sqlite">SQLite</a>数据库的JavaScript接口的子模块</li>
<li><a href="qtquick-particles-qmlmodule.html">Particles</a> - 为QML应用程序提供一个粒子系统</li>

<li><a href="qttest-qmlmodule.html">Tests</a> - 用于测试QML应用程序的类型。</li>
</ul>
<a name="basic-types"></a><a name="basic-types"></a>
<h2 id="basic-types">基本类型</h2>
<p>已经有很多基本类型<a href="../qtqml/qtqml-typesystem-basictypes.html">由QML语言默认支持了</a>。</p>
<p>除此之外，导入<code>QtQuick</code>后还会提供了以下基本类型:<div class="table"><table class="annotated">

</table></div>
</p>
<a name="object-types"></a>
<h2 id="object-types">对象类型</h2>
<p><code>QtQuick</code>导入后提供的所有对象类型都基于<a href="qml-qtquick-item.html">Item</a> 类型，Item类型本身派生自<a href="../qtqml/qml-qtqml-qtobject.html">QtObject</a>。当您导入<code>QtQuick</code>时，Qt QML模块提供的<a href="../qtqml/qtqml-qmlmodule.html#object-types">QML 对象类型</a>（例如<a href="../qtqml/qml-qtqml-qtobject.html">QtObject</a>和<a href="../qtqml/qml-qtqml-component.html">Component</a>）也可用。</p>
